Abstract

L'invention concerne une station de base pour un système de télécommunications mobiles. La station de base comprend un montage de circuits configuré pour communiquer avec au moins un équipement d'utilisateur. Le montage de circuits est configuré en outre pour définir un premier espacement de sous-porteuses pour la transmission d'au moins un signal de synchronisation, et définir un second espacement de sous-porteuses pour une transmission sur un canal de diffusion physique, le premier espacement de sous-porteuses étant différent du second espacement de sous-porteuses.
